Description
Solvent Yellow 12 is a synthetic organic dye characterized by its brilliant green yellow to red light yellow color. It is soluble in ethanol, acetone, and benzene, and has a melting point of 97°C when crystallized from ethanol. In concentrated sulfuric acid, it turns to a red light brown color, which upon dilution, results in a red yellow precipitation. Solvent Yellow 12 exhibits good light fastness and heat resistance, with a temperature range of 80°C to 140°C.
Uses
Used in the Mineral Oil Industry:
Solvent Yellow 12 is used as a coloring agent for mineral oil, grease, and paraffin wax. Its application is due to its ability to impart a vibrant and stable color to these products, enhancing their visual appeal and aiding in identification.
Used in the Chemical Industry:

Check Digit Verification of cas no
The CAS Registry Mumber 6370-43-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6370-43:
(6*6)+(5*3)+(4*7)+(3*0)+(2*4)+(1*3)=90
90 % 10 = 0
So 6370-43-0 is a valid CAS Registry Number.
